ABSTRACT

A communication terminal apparatus capable of registering sender&#39;s e-mail addresses upon receiving e-mails including the e-mail address registration instruction information in the subject. The communication terminal apparatus relieves users from the cumbersome task of manually inputting the recipient&#39;s e-mail address to the e-mail address storage unit  17  and achieves simple e-mail address registration process in a shorter time. The communication terminal apparatus includes the subject determination unit  16  for detecting the e-mail address registration instruction information from a received e-mail, the e-mail parser  13  for acquiring the sender&#39;s e-mail address from the received e-mail, and the sender&#39;s e-mail address registration unit  18  for registering the sender&#39;s e-mail address of the received e-mail with the e-mail address storage unit  17  where the subject determination unit  16  detects the e-mail address registration instruction information.

BACKGROUND OF THE INVENTION

This invention relates to a communication terminal apparatus and an image forming apparatus capable of sending and receiving e-mails.

A multifunction device capable of sending and receiving e-mails as well as scanning and forming images has a so-called scan-and-e-mail function for sending scanned image data as image files attached to an e-mail. The scan-and-e-mail function is frequently used by users, and is one of the functions having high utility value. The scan-and-e-mail function enables the user of the multifunction device to attach scanned image data as image files to an e-mail with the user's own e-mail address specified as the recipient's e-mail address Thus, the user can easily store the received image files in a PC or server, forward the files, and as such.

The scan-and-e-mail function requires a document to be scanned for the generation of image data by the multifunction device and an e-mail address to be specified as the recipient's e-mail address with the multifunction device. To obtain the recipient's e-mail address, generally employed are methods such as follows: that the e-mail address is directly input with the use of operation buttons provided with the multifunction device when the e-mail is sent; that e-mail addresses expected to be specified as recipient's e-mail addresses are previously stored in the multifunction device as an e-mail address list so that the user may select a particular e-mail address from the list when the e-mail is sent, as described in the specification of Japanese Patent Application Publication H05-316145; and that the user pushes a one-touch button previously setting a particular e-mail address with the multifunctional device.

With the direct input method as described above, however, the user is required to input a complicated e-mail address, character by character, in alphabet with the use of the operation buttons provided with the multifunction device. Even with the method of selecting an e-mail address from the list or the method of pushing the one-touch button, the user is required to input complicated e-mail addresses, character by character, in alphabet with the use of the operation buttons provided with the multifunction device at the time of previously registering e-mail addresses. That is, whichever of these prior art methods is employed, the user is required to directly input e-mail addresses by pushing the operation buttons provided with the multifunction device.

This invention has been made to solve such problem that no matter which of the above methods is employed, the user is required to input complicated e-mail addresses, character by character, in alphabet by pushing the operation buttons provided with the multifunction device so as to specify a recipient's e-mail address.

BRIEF SUMMARY OF THE INVENTION

This invention relates to a communication terminal apparatus, capable of sending and receiving e-mails, including an e-mail address storage unit for previously storing e-mail addresses that can be specified as recipients' e-mail addresses, wherein the communication terminal apparatus comprises an instruction information detection unit for detecting an e-mail address registration instruction information from a received e-mail, an e-mail address acquisition unit for acquiring the sender's e-mail address from the received e-mail, and an e-mail address registration unit for registering the sender's e-mail address of the received e-mail with the e-mail address storage unit.

A user can register his or her e-mail address with the e-mail address storage unit of the communication terminal apparatus by sending an e-mail containing the instruction information in the subject to the communication terminal apparatus. This invention is advantageous in relieving the user from a cumbersome task of inputting complicated e-mail addresses, character by character, in alphabet by pushing the operation buttons, and realizing a simple registration process in a shorter time. Furthermore, mistakes in inputting e-mail addresses can be avoided, and a highly convenient multifunction device is provided.

DETAILED DESCRIPTION OF THE INVENTION

Particular embodiments according to this invention is hereinafter described in details with reference to the figures.

The First Embodiment

FIG. 1 is the block diagram showing the structure of a multifunction device according to the first embodiment of this invention. A multifunction device 100 capable of sending and receiving e-mails as well as scanning and forming images is structured as shown in FIG. 1. Components forming the multifunction device 100 and functions thereof are described hereinbelow.

In FIG. 1, an e-mail receiver unit 11 receives an e-mail from an external apparatus, not shown. An e-mail accumulation unit 12 is a memory to accumulate, i.e., hold, an e-mail received by the e-mail receiver unit 11. An e-mail parser 13 receives the received e-mail from the e-mail accumulation unit 12, and parses content of the received e-mail so as to extract therefrom a sender's e-mail address and a subject and to store the extracted sender's e-mail address in a sender's e-mail address accumulation unit 14 and the extracted subject in a subject accumulation unit 15. The sender's e-mail address accumulation unit 14 receives the sender's e-mail address from the e-mail parser 13 and temporarily stores the e-mail address. The subject accumulation unit 15 receives the subject from the e-mail parser 13 and temporarily stores the subject.

The subject determination unit 16 determines whether the extracted subject is the same as a subject previously registered with the subject determination unit 16. Where the extracted subject is the same thereas, the subject determination unit 16 notifies the sender's e-mail address registration unit 18 of a registration instruction. An e-mail address storage unit 17 is a memory to additionally store a plurality of e-mail addresses. The sender's e-mail address registration unit 18 registers the sender's e-mail address with the e-mail address storage unit 17 upon receiving the registration instruction from the subject determination unit 16. A received e-mail deletion unit 21 deletes the received e-mail stored in the e-mail accumulation unit 12 upon receiving a notification of e-mail address registration process completion, described later, from a control unit.

A control unit 22 controls the overall operation of the multifunction device, and more particularly, in the present embodiment, the control unit 22 monitors the e-mail address storage unit 17 upon receiving a notification of e-mail address registration process commencement from the subject determination unit 16, and notifies the received e-mail deletion unit 21 and an e-mail generation unit 31 of the e-mail address registration process completion when the sender's e-mail address has been registered with the e-mail address storage unit 17. An operation unit 23 is an operation panel for a user to operate and give instructions to the multifunction device. A display unit 24, arranged on the operation unit 23, is a display panel to display status and operation result of the multifunction device, thus informing the user thereof. An image scanner unit 25 is an image scanning mechanism to retrieve image data from a document to be scanned.

An image generation unit 26 is a print engine mechanism for printing out prescribed image data. The e-mail generation unit 31 generates an e-mail. Particularly in the present embodiment, the e-mail generation unit 31, upon receiving the notification of e-mail address registration process completion from the control unit 22, generates an e-mail to be sent to the e-mail address, registered in the e-mail address registration process, with an attached transmission message for notifying the e-mail address registration completion. The e-mail sender unit 32 sends the e-mail generated by the e-mail generation unit 31 to a prescribed recipient.

The operation of the multifunction device 100 according to the present embodiment will be hereinafter described. FIG. 2 is the flowchart showing the overall operation of the multifunction device of the first embodiment. Steps S1 through S7 will be described in details in the order of steps with reference to FIG. 1. FIG. 3 is the conceptual diagram showing the e-mail received externally in the first embodiment of this invention.

The multifunction device 100 of the present embodiment receives, for example, the e-mail shown in FIG. 3 from an external apparatus, now shown, via the e-mail receiver unit 11. The received e-mail is stored in the e-mail accumulation unit 12. The received e-mail can be displayed on the display unit 24 upon operation of the operation unit 23, and can be printed by the image forming unit 26. The received e-mail is transferred to the e-mail parser 13, and step S1, namely, the operation of the e-mail parser 13, is performed. The operation of step S1 will be hereinafter described in details.

FIG. 4 is the flowchart showing the operation of the e-mail parser according to the first embodiment of this invention.

In step S1-1, the e-mail parser 13 extracts the sender's e-mail address from the received e-mail. For example, the e-mail parser 13 extracts abcdefg@123.com from the e-mail shown in FIG. 3.

In step S1-2, the e-mail parser 13 stores the extracted sender's e-mail address in the sender's e-mail address accumulation unit 14.

In step S1-3, the e-mail parser 13 determines whether the subject is included in the received e-mail. Where the subject is included therein, step S1-4 is proceeded to. Where not included, this flow is terminated. In the example of FIG. 3, the subject “MARR” is included.

In step S1-4, the e-mail parser 13 extracts the subject from the received e-mail. In the example, the subject “MARR” is extracted from the e-mail shown in FIG. 3.

In step S1-5, the e-mail parser 13 stores the subject extracted from the received e-mail in the subject accumulation unit 15, and then terminates this flow.

Referring back to FIG. 2, the subject determination unit 16 subsequently takes over the operation, and performs step S2, namely, the operation of the subject determination unit 16. Step S2 will be hereinafter described in details. FIG. 5 is the flowchart showing the operation of the subject determination unit according to the first embodiment of this invention

In step S2-1, the subject determination unit 16 monitors the subject accumulation unit 15 to see if the subject is stored therein. Where the subject is detected therein, step S2-2 is proceeded to. The subject “MARR” should be detected in the e-mail shown in FIG. 3 in the example.

In step S2-2, the subject determination unit 16 determines whether the subject is the same as the subject previously stored in the subject determination unit 16. Where the subject is the same thereas, step S2-3 is proceeded to. Where not, this flow is terminated. In the example, suppose that the subject “MARR”, which stands for “Mail Address Registration Requirement” meaning a request for e-mail address registration, is previously stored in the subject determination unit 16. In such case, the subject “MARR” of the e-mail shown in FIG. 3 is the same as the previously stored subject “MARR”, and therefore, step S2-3 is proceeded to.

In step S2-3, the subject determination unit 16 notifies the sender's e-mail address registration unit 18 of the registration instruction.

In step S2-4, the subject determination unit 16 further notifies the control unit 22 of the e-mail address registration process commencement, and terminates this flow.

Referring back to FIG. 2, the sender's e-mail address registration unit 18 subsequently takes over the operation, and performs step S3, namely, the operation of the sender's e-mail address registration unit 18. Step S3 will be hereinafter described in details. FIG. 6 is the flowchart showing the operation of the sender's e-mail address registration unit according to the first embodiment of this invention.

In step S3-1, the sender's e-mail address registration unit 18 waits for receiving the registration instruction from the subject determination unit 16. Once receiving the registration instruction, step S3-2 is proceeded to.

In step S3-2, the sender's e-mail address registration unit 18 additionally registers the sender's e-mail address in the sender's e-mail address accumulation unit 14 with the e-mail address storage unit 17, and terminates this flow.

Referring back to FIG. 2, control unit 22 subsequently takes over the operation, and performs step S4, namely, the operation of the control unit 22 monitoring the e-mail address registration process, while the above-mentioned step S3 is performed. Step S4 will be hereinafter described. FIG. 7 is the flowchart showing the operation of the control unit monitoring the e-mail address registration process according to the first embodiment of this invention.

In step S4-1, the control unit 22 waits for receiving the notification of e-mail address registration process commencement from the subject determination unit 16, and proceeds to step S4-2 upon receiving the notification.

In step S4-2, upon receiving the notification, the control unit 22 stands by monitoring the status of the e-mail address storage unit 17. The control unit 22 proceeds to step S4-3 upon detecting the completion of the e-mail address registration process for registration with the e-mail address storage unit 17.

In step S4-3, the control unit 22 notifies the received e-mail deletion unit 21 and the e-mail generation unit 31 of the e-mail address registration process completion, meaning that the sender's e-mail address has been additionally reregistered with the e-mail address storage unit 17, and terminates this flow.

Referring back to FIG. 2, the received e-mail deletion unit subsequently takes over the operation, and performs step S5, namely, the operation of the received e-mail deletion unit 21. Step S5 will be hereinafter described in details. FIG. 8 is the flowchart showing the operation of the received e-mail deletion unit according to the first embodiment of this invention.

In step S5-1, the received e-mail deletion unit 21 waits for receiving the notification of e-mail address registration process completion from the control unit 22, and proceeds to step S5-2 upon receiving the notification.

In step S5-2, the received e-mail deletion unit 21 deletes the received e-mail stored in the e-mail accumulation unit 12, and terminates this flow.

Referring back to FIG. 2, the e-mail generation unit 31 takes over the operation, and performs step S6, namely, the operation of the e-mail generation unit 31. Step S6 will be hereinafter described in details. FIG. 9 is the flowchart showing the operation of the e-mail generation unit according to the first embodiment of this invention.

In step S6-1, the e-mail generation unit 31 waits for receiving the notification of e-mail address registration process completion from the control unit 22, and proceeds to step S6-2 upon receiving the notification.

In step S6-2, the e-mail generation unit 31 determines whether a prescribed transmission message is previously registered with the e-mail generation unit 31. Where the prescribed transmission message is registered therewith, step S6-3 is proceeded to. Where not, this flow is terminated. For example, suppose that the transmission message “Mail Address Registration Process has finished”, meaning that the e-mail address registration has been finished, is previously registered with the e-mail generation unit 31. In such case, step S6-3 is proceeded to.

In step S6-3, the e-mail generation unit 31 sets the recipient's e-mail address to the e-mail address stored in the sender's e-mail address accumulation unit 14.

In step S6-4, the e-mail generation unit 31 subsequently sets the body of the e-mail to the transmission message, and terminates this flow. In the example, the body of the e-mail is set to “Mail Address Registration Process has finished”.

Referring back to FIG. 2, the e-mail sender unit 32 takes over the operation, and performs step S7, namely, the operation of the e-mail sender unit 32. Step S7 will be hereinafter described in details. FIG. 10 is the flowchart showing the operation of the e-mail sender unit according to the first embodiment of this invention.

In step S7-1, the e-mail sender unit 32 monitors the e-mail generation unit 31 to see if the e-mail to be sent is stored therein. Where the e-mail to be sent is stored therein, step S7-2 is proceeded to.

In step S7-2, the e-mail sender unit 32 determines whether the recipient's e-mail address has been set. Where the recipient's e-mail address has been set, step S7-3 is proceeded to. Where not, this flow is terminated.

In step S7-3, the e-mail sender unit 32 determines whether the body of the e-mail has been set. Where the body of the e-mail has been set, step S7-4 is proceeded to. Where not, this flow is terminated.

In step S7-4, the e-mail sender unit 32 sends the e-mail in the e-mail generation unit 31 to the specified e-mail address. FIG. 11 is the conceptual diagram of the registration completion notification e-mail. More particularly, FIG. 11 is the conceptual diagram showing the e-mail, as the registration completion notification e-mail of registration with the e-mail address storage unit 17, to be sent from the e-mail sender unit 32 to the specified e-mail address. The e-mail in FIG. 11 has the recipient's e-mail address and the sender's e-mail address having been replaced with each other when compared to the e-mail in FIG. 3, and furthermore, the e-mail in FIG. 11 has the subject “Re: MARR” meaning the completion of registration and the body of the e-mail “Mail Address Registration Process has finished”. “One-touch dial number” may also be added to the subject or the body of the e-mail so as to register the e-mail address with the specified one-touch dial number such as “03”.

Accordingly, the multifunction device 100 according to the present embodiment enables the user to have his or her e-mail address automatically registered with the e-mail address storage unit 17 of the multifunction device 100 by sending the e-mail containing the subject “MARR” from the user's e-mail system to the multifunction device 100 where the user wants to register his or her e-mail address with the e-mail address storage unit of the multifunction device.

The multifunction device 100 according to the present embodiment of this invention stores in the e-mail address storage unit the sender's e-mail address of the received e-mail only if the subject of the received e-e-mail contains “MARR” (instruction information). A system administrator of the multifunction device is thus relieved from inquiring of each sender of received e-mails whether or not e-mail addresses thereof should be additionally registered when a large number of unnecessary e-mail messages, such as spam mails, are received. That is, the multifunction device 100 does not indiscriminately register sender's e-mail addresses of received e-mails.

In order to register the e-mail address with the multifunction device 100 according to the present embodiment of this invention, the multifunction device 100 has only to receive an e-mail containing the instruction information, such as “MARR”, in the subject from the user who wants to register his or her e-mail address. Therefore, the user can register his or her e-mail address with the multifunction device 100 by sending a small size e-mail without relying on the body of the e-mail, and thus the multifunction device 100 alleviates the network load of network which e-mails for e-mail address registration pass through.

The multifunction device 100 according to the present embodiment of this invention deletes the received e-mail stored in the e-mail accumulation unit after completing the sender's e-mail address registration process. Consequently, the multifunction device 100 not only occupies smaller memory space for keeping received e-mails but also quickly goes into a status ready to receive further e-mails.

The multifunction device 100 according to the present embodiment of this invention sends the registration completion notification e-mail to the sender's e-mail address after completing the sender's e-mail address registration process. Consequently, the user is enabled to easily recognize that a series of registration process has been finished.

As hereinabove described, the multifunction device 100 according to the present embodiment of this invention registers the user's own e-mail address with the e-mail address storage unit thereof where the user sends the e-mail containing the instruction information in the subject to the multifunction device. Furthermore, the multifunction device 100 relieves the user from a cumbersome task of inputting a complicated e-mail address through pushing the operation buttons, character by character, in alphabet. Thus, the multifunction device 100 results in a highly convenient multifunction device with shorter registration time, simpler registration process, and less likely to make mistakes in inputting the e-mail address since the multifunction device 100 registers the user's e-mail address with the e-mail address storage unit thereof where the user sends the e-mail containing the instruction information in the subject to the multifunction device 100.

The Second Embodiment

Although not specifically shown in the first embodiment, e-mail addresses stored in the e-mail address storage unit 17 (FIG. 1) are displayed in the display unit 24 (FIG. 1) sorted in alphabetical order when the user requests to display an e-mail address list with the use of the operation unit 23 (FIG. 1) in the first embodiment. The user then selects an e-mail address that the e-mail is to be sent to from the displayed e-mail address list with the use of a scroll function of the operation buttons on the operation unit 23 (FIG. 1). With such e-mail address selection method, however, it may be troublesome for the user to specify the recipient's e-mail address. Especially where the user has registered e-mail addresses having a prefix of v or w, the more e-mail addresses are contained in the e-mail address list, it is the more likely that the user finds it troublesome to select an e-mail address.

The second embodiment is structured to display the latest registered e-mail address at the top of the display unit where e-mail addresses are requested to be displayed within less than the prescribed time after the e-mail address registration so that the e-mail address can be easily selected where the user wants to use the e-mail address right after its registration. On the other hand, e-mail addresses are displayed in ordinary alphabetical order where e-mail addresses are requested to be displayed not less the prescribed time after the e-mail address registration. The multifunction device according to the present embodiment is structured as follows to achieve the above mentioned purpose.

FIG. 12 is the block diagram showing the structure of the multifunction device according to the second embodiment of this invention. A multifunction device 200 capable of sending and receiving e-mails as well as scanning and forming images is structured as shown in FIG. 12. As shown in FIG. 12, the multifunction device 200 includes a registration time determination unit 42, an information selection unit 43 for selecting information registered within the prescribed time, and a display order determination unit 44 in addition to those that the multifunction device 100 (FIG. 1) has. Furthermore, a register A, a register B, and a register C are arranged in a control unit 41, corresponding to the control unit 22 (FIG. 1) of the first embodiment. The other components are the same as the first embodiment except the above. Thus, only the components different from the first embodiment are hereinbelow described in details.

The control unit 41 controls the entire operation of the multifunction device 200, and particularly in the present embodiment, the control unit 41 includes the register A, the register B, and the register C in the interior of the control unit 41 in addition to functions of the control unit of the first embodiment. The register A keeps a time as to when the latest registered e-mail address was registered with the e-mail address storage unit 17. The register B keeps a current time. The register C keeps the prescribed time which the register C is set to. The control unit 41 performs a prescribed control program stored in a ROM, not shown, and initiates the registration time determination unit 42, the information selection unit 43, and the display order determination unit 44.

The registration time determination unit 41 determines the time as to when the e-mail address stored in the e-mail address storage unit 17 was registered. The information selection unit 43 determines (namely, selects the e-mail address) whether the e-mail address stored in the e-mail address storage unit 17 was registered within less than the prescribed time stored in the above mentioned register C before the current time kept in the register B. The display order determination unit 44 determines the order of the e-mail addresses stored in the e-mail address storage unit 17 based on prescribed rules as follows.

The prescribed rules are as follows. Rule 1: Where the registration time of the latest registered e-mail address stored in the e-mail address storage unit 17 is within less than the prescribed time stored in the register C before the current time, the latest registered e-mail address is put at the top, and the rest of e-mail addresses are sorted in alphabetical order. Rule 2: Where the registration time of the latest registered e-mail address stored in the e-mail address storage unit 17 is not less than the prescribed time stored in the register C before the current time, all the e-mail addresses are sorted in alphabetical order.

The display order determination unit 44 will be hereinafter described with reference to the figures. FIG. 13 is the diagram for explaining the function of the display order determination unit. TABLE A shows the e-mail address storage unit 17 (FIG. 12) displayed on the display unit 24 (FIG. 12) as they are. TABLE B shows the e-mail address storage unit 17 (FIG. 12) after a sort is performed based on the Rule 1 of the prescribed rules. TABLE C shows the e-mail address storage unit 17 after a sort is performed based on the Rule 2 of the prescribed rules. In TABLE B and TABLE C, an e-mail address in an elongated circle is the latest registered e-mail address.

As shown in TABLE A, the e-mail address list is displayed in alphabetical order regardless of the registration time of e-mail address where the e-mail addresses stored in the e-mail address storage unit 17 (FIG. 12) are displayed on the display unit 24 (FIG. 12) as they are. As shown in TABLE B, where the latest registered e-mail address in the elongated circle was registered within less than the prescribed time stored in the register C before the current time, the latest registered e-mail address is displayed at the top and the rest of e-mail addresses are displayed in alphabetical order. As shown in TABLE C, where the latest registered e-mail address in the elongated circle was registered not less than the prescribed time stored in the register C before the current time, all of the e-mail addresses are displayed in alphabetical order.

The operation of the multifunction device according to the second embodiment will be hereinafter described. The multifunction device 200 according to the present embodiment is capable of sending and receiving e-mails as well as scanning and forming images. The registration of the sender's e-mail address of the received e-mail, the deletion of the received e-mail from the accumulation unit, and the transmission of the e-mail address registration completion notification e-mail to the sender's e-mail address are the same as those of the first embodiment, and thus are omitted for brevity.

FIG. 14 is the flowchart showing the displaying operation of the multifunction device according to the second embodiment of this invention. The displaying operation of the multifunction device 200, including the operations of the registration time determination unit 42, the information selection unit 43, and the display order determination unit 44, which are initiated and generated by the control unit 41, will be described from step S5-1 to S5-9 in the order of steps with reference to the FIG. 12.

In step S5-1, the control unit 41, upon detecting the completion of the e-mail address registration process with the e-mail address storage unit 17, waits for the display request of the e-mail address list from the user via the control unit 23, and proceeds to step S5-2 upon receiving the display request.

In step S5-2, the registration time determination unit 42 reads and sends to the control unit 41 the time as to when the latest registered e-mail address was registered with the e-mail address storage unit 17.

In step S5-3, the control unit 41 receives from the registration time determination unit 42 the time as to when the latest registered e-mail address was registered, and stores the registration time in the register A.

In step S5-4, the control unit 41 reads out the current time from a clock in the control unit 41.

In step S5-5, the control unit 41 stores the current time in the register B.

In step S5-6, the information selection unit 43 determines whether the latest registered e-mail address was registered within less than the prescribed time, such as within less than 30 minutes, before the current time. Where the latest registered e-mail address was registered within less than the prescribed time, step S5-7 is proceeded to. Where the latest registered e-mail address was registered not less than the prescribed time, step S5-8 is proceeded to. That is, the difference between the register B and the register A is compared with the register C. In the example, if the difference between the register B and the register A is 15 minutes, step S5-7 is proceeded to. If the difference is 45 minutes, step S5-8 is proceeded to.

In step S5-7, the display order determination unit 44 determines to arrange the latest registered sender's e-mail address at the top of the e-mail address storage unit 17, and sort the remaining e-mail addresses in alphabetical order.

On the other hand, in step S5-8, the display order determination unit 44 determines to sort all the registered e-mail addresses in alphabetical order.

In step S5-9, the control unit 41 sorts the e-mail addresses in the e-mail address storage unit 17 based on the decision of the display order determination unit 44, and sends the sorted e-mail addresses to the display unit 24 to have the display unit 24 display the sorted e-mail addresses, and then terminates this flow. The result of the sorted e-mail addresses is shown in FIG. 13.

In the above example, although only a single latest registered e-mail address is arranged to be displayed at the top of the list, it may also be configured to display at the top of the list a plurality of all the e-mail addresses that have been newly registered within less than a certain time such as, e.g., 30 minutes before the display request upon searching for such newly registered e-mail addresses. Such configuration may be effective for a multifunction peripheral (MFP) used in a large office.

As hereinabove described, the multifunction device according to the present embodiment displays the latest registered e-mail address at the top when operated to display the e-mail addresses right after the e-mail address registration, and thus, the user who wants to select the e-mail address right after the user has registered the e-mail address is relieved from a cumbersome task of searching for the e-mail address by pressing the operation buttons previously equipped with the multifunction device. Therefore, the user can register and use the e-mail address in a simple process in a shorter time as well as avoid making mistakes in inputting e-mail addresses. Thus, the present embodiment provides a highly convenient multifunction device.

The Third Embodiment

In the first embodiment, the user sends the e-mail containing the subject “MARR” from the user's e-mail system to the multifunction device 100 (FIG. 1) so that the user's e-mail address is automatically additionally registered with the e-mail address storage unit 17 (FIG. 1) where the user wants to register his or her e-mail address in the e-mail address storage unit 17 (FIG. 1). In an actual situation in which the multifunction device is used, the user may want to delete the registration of e-mail address which was once registered. Taking such situation into account, the present embodiment has an e-mail address registration deletion function in addition to the functions of the multifunction device of the first embodiment. To achieve such purpose, the multifunction device according to the third embodiment is structured as follows.

FIG. 15 is the block diagram showing the structure of the multifunction device according to the third embodiment of this invention. A multifunction device 300 capable of sending and receiving e-mails as well as scanning and forming images is structured as shown in FIG. 15. Only functions of the multifunction device 300 which are added or different from the first embodiment will be hereinafter described. Components having the same functions as the first embodiment are denoted by the same reference numerals as the first embodiment, and the description thereof is omitted for brevity.

Referring to FIG. 15, the subject determination unit 54 determines whether the subject extracted by the e-mail parser 13 is the same as the subjects contained in the subject determination unit 54. Where the subject is the same thereas, the subject determination unit 54 gives the registration instruction to the sender's e-mail address registration unit 18, or a registration deletion instruction (newly added in the third embodiment) to a sender's e-mail address registration deletion unit 56. The sender's e-mail address registration deletion unit 56 deletes (newly added in the third embodiment) the registration of the sender's e-mail address from the e-mail address storage unit 17 upon receiving the notification of registration deletion instruction (newly added in the third embodiment) from the subject determination unit 54.

A control unit 58 controls the entire operation of the multifunction device. The control unit 58 monitors the e-mail address storage unit 17 upon receiving the notification of e-mail address registration process commencement from the subject determination unit 54. The control unit 58, upon finding that the sender's e-mail address has been registered with the e-mail address storage unit 17, notifies the received e-mail deletion unit 57 and an e-mail generation unit 59 of the e-mail address registration process completion. Furthermore, the control unit 58 monitors the e-mail address storage unit 17 upon receiving the notification of e-mail address registration deletion process commencement (newly added in the third embodiment) from the subject determination unit 54. The control unit 58, upon detecting that the sender's e-mail address has been deleted from the e-mail address storage unit 17, notifies the received e-mail deletion unit 57 and the e-mail generation unit 59 of the e-mail address registration deletion process completion (newly added in the third embodiment).

The e-mail generation unit 59 generates an e-mail. The e-mail generation unit 59, upon receiving the notification of e-mail address registration process completion, generates the e-mail to be sent to the e-mail address registered in the e-mail address registration process with an attached message for the purpose of notifying the e-mail address registration completion.
